Sediments and Phytoplankton Off Coast of Denmark

Sediments can be seen off the coast of Denmark and the Jutland Peninsula. Nearest the shoreline they are greyish brown in color, and become progressively greener as they diffuse into the North Sea. Further west, the greenish blue color of the water appears to be due to phytoplankton rather than coloring by sediments, although the presence of sediments in the water often brings increased nutrients which, in turn, lead to increased phytoplankton growth.
